How to effectively control the quality of Geogrid in the process of construction
3 when laying geosynthetics, the direction of high strength should be placed in the main stress direction of the embankment.4 geosynthetic materials should be paved after the design requirements of the back section, and timely coverage with sand.5 rolling and transportation equipment, such as rolling or walking directly on geosynthetics.6 the width of the lap and anchor meet the requirements.7 of the original land drainage should be formed 4% of the crown.8 shop geosynthetics are hidden works, the construction process should have the quality control personnel on-site monitoring and do a good job of hidden engineering inspection records, report to the supervisor can be recognized for the next construction process.
2 the surface of the bearing surface of the geosynthetics shall be leveled and compacted, and the hard and protruding surface shall be removed.
1 raw material quality in accordance with the required frequency and standard sampling, strengthening the construction of protection against pollution and destruction.
